Nomos

Kroton's early silver issues belong to the Achaean colonial tradition of incuse coinage — a technique almost certainly developed in southern Italy rather than the Greek mainland, and used exclusively by a cluster of neighboring poleis in Magna Graecia. The incuse reverse, a mirror intaglio of the obverse type, required precise die alignment and a level of technical coordination that distinguishes these coins from nearly all contemporary Greek minting practice.

Kroton was among the wealthiest cities on the Italian toe by the late sixth century, its prominence tied as much to the Pythagorean community established there around 530 BC as to its commercial dominance. The school's influence on civic life was substantial enough that later ancient sources credited Pythagorean doctrine with shaping the city's political order during precisely this minting period.
